Description

FIELD OF THE INVENTION

The The present invention relates to compositions containing spherical powder components contain.

BACKGROUND

A Primer composition can be applied to the face and other parts of the body be applied to balance the skin tone and the skin tissue and hide pores, bumps, fine lines and the like. A primer composition is also applied to the skin to provide moisture, to balance the oil content of the skin and protection against the adverse effects of sunlight, wind and to offer other environmental factors.

primer compositions in the form of solids, such as loose powders and compact powders popular with consumers who like the fresh, light feeling on the Enjoy the skin. Solid primers packaged in powder cans are special suitable because such products can be carried for use.

Cosmetic compositions containing spherical powders are known as in JP H6-271419 . JPA 60-255712 . JPA 9-100213 . JPA 10-338616 and JPA 11-209243 , Although the use of spherical powder promotes smooth spreading of the compositions when applied to the skin, the use generally does not contribute to the good adhesion of the composition to the skin. The use of larger amounts of binders can provide improved adhesion, but can also impart a heavy, sticky feel.

Based in the above, there is a need for a solid cosmetic composition, in terms of distributability when applied to the skin, the good adhesion to the skin and the fresh, light feeling on the skin Skin has balanced benefits.

Of the The state of the art nowhere offers all the advantages and benefits of present invention.
